Pshe consists of a circular plate group and shell. The plate group, enclosed in the pressure vessel, is the core of the heat exchanger. As heat transfer components, plates determine the heat transfer performance of the heat exchanger. Shell is the essential for the temperature, pressure capacity and safe and reliable operation.
Based on specific operating parameters, media flow paths can be set properly, which ensures the reasonable match of heat transfer efficiency and the resistance loss, and at the same time minimizes equipment investment and operating costs.
Plate & frame type heat exchanger is a fully welded plate and frame heat exchanger, which consists of a fully welded plate group and removable covers. Four covers can be opened from four directions for the inspection, maintenance and cleaning of the plate group. By adjusting the flow structure and the installation position of the partition, it is suitable for different working conditions.
Plate corrugation will match with medium properties.
With compact structure, this kind of heat exchanger has high heat transfer efficiency.
We have hundreds of types of plate and gasket for your choice, with the most complete range, perfect quality and irresistible prices.

Semi-welded plate heat exchanger consists of a series of cassettes-plate pairs, which formed by two plates laser welded together along the sealing groove. The aggressive medium flows inside the cassette, only in contact with a special designed ring gasket. Each cassette is fitted with a gasket. The other medium flows in the gasketed channels. Two media flow reversely in adjacent channels, between which heat transfer will take place.
It is widely used in the evaporation and condensation of ammonia and freon refrigerant, industrial evaporation and condensation, water-cooled oil cooler, and general cooling and heating of high temperature, high pressure and strong corrosive media in one channel.
Technical advantages
Our semi-welded plate heat exchanger adopts the world's most advanced laser welding machine and modern laser beam welding process. Compared with other welding methods, laser beam welding process has the advantages of little deformation after welding, high welding quality, and small stress. It is particularly suitable for high pressure and corrosive conditions.
